Maintain clean compressed air and dependable compressor performance with the Sullair Separator Replacement - 250034-122. This air oil separator element is designed for Sullair rotary screw air compressors and removes lubricating oil from compressed air inside the separator vessel before it exits the system. By capturing fine oil mist and returning it to the compressor lubrication circuit, this separator helps reduce oil carryover, support air quality, and maintain efficient compressor operation.

  • High Efficiency Oil Separation – Captures fine oil aerosols from compressed air to help maintain clean air output and proper lubricant circulation.
  • Reduced Oil Carryover – Helps return lubricant to the compressor sump while keeping residual oil levels in compressed air extremely low.
  • Supports Compressor Efficiency – Proper separation helps maintain system pressure balance and protect downstream air equipment.
  • OEM Compatible Fitment – Designed for Sullair rotary screw compressors to ensure reliable installation and dependable separation performance.

Protect compressor efficiency and maintain consistent compressed air quality with the Sullair Separator Replacement - 250034-122, a critical maintenance component engineered to reduce oil carryover and support long term compressor reliability.

Frequently Asked Questions

Is the 250034-122 separator compatible with my Sullair compressor?

The 250034-122 air-oil separator is designed for Sullair rotary screw compressors that require this exact part number. If your compressor’s service manual lists 250034-122, this replacement separator is the correct fit. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility.     

What does the 250034-122 separator do?

This separator uses coalescing filtration to remove oil aerosols from the compressed air stream and return the oil back to the lubrication system. This helps reduce oil carryover and improves air quality leaving the compressor.

How often should I replace the 250034-122 separator?

Water separators are commonly replaced about every 4,000 hours, depending on operating conditions and maintenance practices. They should be inspected regularly and replaced if performance drops, clogging occurs, or moisture carryover increases.

Is this an OEM part?

This is an OEM-equivalent replacement separator designed to meet or exceed the performance standards of the original Sullair component while offering a cost-effective alternative.

Why is it important to replace my separator regularly?

Over time, separators become saturated with oil and contaminants. A worn separator can increase pressure drop, reduce efficiency, and allow oil to pass into the compressed air system, which can impact downstream equipment and air quality. 

How difficult is it to install?

Installation is typically straightforward for a trained technician. The separator installs inside the separator vessel or housing as a direct replacement element. Always shut down and depressurize the compressor before performing maintenance.

Do you carry other parts for Sullair compressors?

Absolutely. We stock air filters, oil filters, separators, lubricants, and more for Sullair compressors. If you don’t see what you need, just ask. We’re happy to help.

How do I know which oil to use in my Sullair compressor?

Stationary rotary screw compressors may have specific oil requirements that differ from reciprocating or portable units. To make sure you’re using the right lubricant for your machine, check out our full guide here: Choosing the Right Oil for your Sullair Compressor. It covers the recommended options for rotary screw compressors and helps you match your compressor with the proper oil.
